Grams of Sugar to Tsp Formula

Choose Grams to teaspoons or Teaspoons to grams. The formulas below use the chosen sugar type’s editable estimate and selected teaspoon volume. King Arthur cup references divided by 48 provide the US-teaspoon presets; packing and moisture affect the approximation.

tsp = (grams) / (d × Vₜₛₚ)
  • US teaspoon = 4.92892159375 mL
  • Metric teaspoon = 5 mL.
  • Granulated sugar: 198 g per US cup → 4.125 g per US tsp (d ≈ 0.8369 g/mL)
  • Powdered/icing sugar, unsifted: 113 g per US cup → approximately 2.3542 g per US tsp (d ≈ 0.4776 g/mL)
  • Brown sugar, light (packed): shared packed-brown reference 213 g per US cup → 4.4375 g per US tsp (d ≈ 0.9003 g/mL)
  • Brown sugar, dark (packed): the same 213 g per US cup reference → 4.4375 g per US tsp (d ≈ 0.9003 g/mL); enter a measured value if your product differs.

* Granulated sugar, US tsp: chosen recipe reference 198 g per US cup → 1 tsp ≈ 4.125 g.

How do you convert grams of sugar to teaspoons? Use tsp = grams ÷ (density × tsp mL); for granulated sugar with US teaspoons, divide grams by 4.125 (since the chosen reference gives 1 US tsp ≈ 4.125 g).

How do you convert teaspoons of sugar to grams? Multiply teaspoons by density × tsp mL; for granulated sugar (US), grams ≈ tsp × 4.125.

Example Problem

Convert 18 g of granulated sugar to US teaspoons.

Use tsp = grams ÷ (d × Vtsp) with d = 198 ÷ 236.5882365 g/mL and Vtsp = 4.92892159375 mL.

tsp = 18 ÷ 4.125 ≈ 4.3636 US tsp
